A Change in %FEV1.0 of responders and non-responders group. B Effect of PEA on improvement of mPAP (ΔmPAP) between responders and non-responders. C The correlation between ΔCTA obstruction score and Δ%FEV1.0. The largest 20 cases regarding the value of %FEV1.0 positive and negative difference before and after PEA was defined as responder and non-responder, respectively. A The difference in value was named as Δ%FEV1.0. B Mean PAP was better improved in the responders group compared to the non-responders group. C In 29 patients in whose CTA obstruction score could be assessed postoperatively, ΔCTA obstruction score and Δ%FEV1.0 were negatively correlated
